This is a really fun riff to play, and pretty easy once you get the hang of it.
I'm actually surprised this hasn't been done yet :—/ Oh well.  Here's my 
interpretation of it...don't tear me apart, 'cause this is my first tab :D

Tuning: (BEADG, but it can be played BADG or BEAD for us four—stringers)

There is really only one riff to this song, and than he just improv's the heck out 
of it, using a LOT of slides.

Main Riff:
G:| —————————————————————————————————
D:| —————————————————————————————————
A:| ———————2———2h3——————————2———2h3——
E:| —————————————————————————————————
B:| —x—x—0———0—————0——0———0———0——————

NOTE: I can't tell if he slaps and pops in this...I don't think he does, but I could
be wrong.  Experiment with it, I guess.  Enjoy!  Comments appreciated!
